A triangle and a rectangle are shown below.

Triangle height is 8cm, base is 6cm

Rectangle length is 12cm

The area of the rectangle is 5 times the area of the triangle.

Work out the width (w) of the rectangle.

The Width = 10cm

Step-by-step explanation:

Area of Triangle = 1/2 * base * height

Area of rectangle = Length * Width

Area of Triangle = 1/2 * 6 * 8 = 24cm^2

From the question:

Area of rectangle = 5 times area of triangle

L * W = 5 * 24

12 * W = 120

12W/12 = 120/12

W = 10cm

w=10 cm

Step-by-step explanation:

Area of the triangle = 1/2*8 cm*6 cm = 24 cm^2

Area of the rectangle=5*24 cm^2=120 cm^2

width*length=120 cm^2

width=120 cm^2 / (12 cm)
